Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, and in particular to a hydraulic press that is easy to adjust. Background Technology

[0002] In modern industrial production, the demand for multi-channel hydraulic systems in large-scale machinery and complex systems is increasingly prominent. Many large pieces of equipment, such as large injection molding machines, sheet metal rolling mills, tunnel boring machines, and aircraft landing gear, require the simultaneous execution of different actions and motion control of multiple actuators. Multi-channel hydraulic systems provide each actuator with an independent hydraulic oil source and control channel, enabling them to work collaboratively to complete complex production or operational tasks. Taking large injection molding machines as an example, the injection process involves multiple precision actions, including mold opening and closing, ejector pin ejection, screw rotation, and injection. Multi-channel hydraulic systems can precisely control the start, stop, speed, and pressure of each action, thereby ensuring the efficiency and precision of the injection molding process and effectively improving product quality and production efficiency.

[0003] Currently, conventional hydraulic presses achieve multi-channel switching primarily through a combination of control components such as multi-way directional valves, solenoid valves, and electro-hydraulic proportional valves. Taking automated packaging machinery as an example, this equipment uses multiple solenoid valves that are energized sequentially according to a preset program, guiding hydraulic oil to different actuators, thereby automating the packaging process.

[0004] However, traditional technologies have revealed some significant shortcomings in practical applications, mainly in terms of complex control logic and a large number of functional components. Taking solenoid valve combination control as an example, to achieve accurate operation of multiple solenoid valves, cumbersome electrical control programs need to be developed, especially in large multi-channel hydraulic systems where the control logic is quite complex. Furthermore, the complex piping connections for installing numerous solenoid valves increase the difficulty of equipment assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hydraulic press that is easy to adjust, with relatively simple control logic and reduced assembly difficulty.

[0006] To solve the above-mentioned technical problems, this utility model provides an easily adjustable hydraulic press, including a hydraulic station, an adjusting plate, a guide plate, and hydraulic working components;

[0007] The regulating plate is provided with a main input channel and multiple regulating channels with input sections connected to the main input channel. The input section of the regulating channel is provided with a first needle valve.

[0008] The guide plate is provided with a main flow channel and multiple branch guide channels with output sections connected to the main flow channel. The output sections of the multiple adjustment channels are connected to the input sections of the multiple branch guide channels one by one.

[0009] The output end of the hydraulic station is connected to the main input channel, the input end of the hydraulic working component is connected to the main flow channel, and the input end of the hydraulic station is connected to the output end of the hydraulic working component.

[0010] As an improvement to the above solution, the diversion channel is equipped with a second needle valve.

[0011] As an improvement to the above solution, both the regulating plate and the guide plate are provided with mounting holes that are perpendicular to and interconnected with the input section of the regulating flow channel or the sub-guide channel. Both the first needle valve and the second needle valve include a plug that is slidably connected to the mounting hole and is used to block the input section of the regulating flow channel or the sub-guide channel, and a drive cylinder installed on the regulating plate or the guide plate and used to drive the plug to switch positions within the mounting hole.

[0012] As an improvement to the above solution, the cylinder output end is provided with a connecting rod that extends into the mounting hole, and the outer diameter of the connecting rod is smaller than the inner diameter of the mounting hole.

[0013] As an improvement to the above solution, the plug is provided with a pressure relief channel that runs through the upper and lower sides of the plug.

[0014] As an improvement to the above scheme, the main input channel is extended front and rear, and the input section of the regulating channel is extended left and right.

[0015] As an improvement to the above scheme, the input sections of the multiple regulating channels are staggered in the front and rear, left and right directions.

[0016] As an improvement to the above scheme, the main flow channel extends forward and backward, and the branch flow channels extend left and right.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0031] like Figures 1 to 5 As shown in the figure, an easily adjustable hydraulic press according to an embodiment of this utility model includes a hydraulic station 100, an adjusting plate 200, a guide plate 300, and a hydraulic working component 400. In practice, the hydraulic station 100 outputs and receives hydraulic oil, providing a medium with pressure energy to the hydraulic working component 400, thereby driving the hydraulic working component 400 to operate. The hydraulic working component 400 is an action execution component in a corresponding hydraulic press, such as a hydraulic cylinder in a hydraulic press, a hydraulic tension pad system in automotive parts manufacturing, or related components in tunnel boring machines and aircraft landing gear. After receiving hydraulic oil with pressure energy, it performs the corresponding action.

[0032] The regulating plate 200 has a main input channel 210 and multiple regulating channels 220 with input sections connected to the main input channel 210. Each regulating channel 220 has a first needle valve 510 at its input section. It should be noted that the number and function of the regulating channels 220 should be determined based on the operational requirements of the hydraulic working component 400. The regulating channels 220 can be machined onto the regulating plate 200 or implemented by externally connecting fixed hydraulic channel modules. In this way, the start, stop, and speed of the hydraulic working component 400 can be controlled separately. This document will not describe the specific number, structure, and working principle of the regulating channels 220 in detail. In fact, the main function of the first needle valve 510 is to control the opening and closing of the pipes in the input section of the regulating channel 220, which can be done manually, pneumatically, or electrically. When a specific regulating channel 220 needs to be selected, only the first needle valve 510 on the input section of that regulating channel 220 needs to be opened, while the other first needle valves 510 are closed. The control logic is relatively simple.

[0033] The guide plate 300 is provided with a main flow channel 310 and multiple branch guide channels 320 whose output sections are connected to the main flow channel 310. The output sections of the multiple regulating channels 220 are connected to the input sections of the multiple branch guide channels 320 in a one-to-one correspondence. In fact, the main flow channel 310 and the branch guide channels 320 can be machined on the guide plate 300; the number of branch guide channels 320 matches the number of regulating channels 220, and the branch guide channels 320 and regulating channels 220 can be connected one-to-one by means of pipes, connecting fittings, seals, etc. In actual operation, a specific regulating channel 220 is selected by operating the first needle valve 510. After the hydraulic oil flows out from the selected regulating channel 220, it flows into the main flow channel 310 through the corresponding branch guide channels 320 and is discharged from the main flow channel 310.

[0034] The output end of the hydraulic station 100 is connected to the main input channel 210, the input end of the hydraulic working component 400 is connected to the main flow channel 310, and the input end of the hydraulic station 100 is connected to the output end of the hydraulic working component 400. With this configuration, only the pipelines connecting the hydraulic station 100, the regulating plate 200, the guide plate 300, and the hydraulic working component 400 need to be laid out. These pipelines can be directly connected to both ends through one or more pipes, reducing the assembly difficulty of the equipment.

[0035] The easily adjustable hydraulic press of this utility model uses a hydraulic station 100, an adjusting plate 200, a guide plate 300, and a hydraulic working component 400 to cooperate with each other. It has multiple adjustable flow channels 220 to choose from, so that the hydraulic working component 400 can be switched between various operating actions. The corresponding action can be achieved by simply controlling the opening of the first needle valve 510. The control logic is relatively simple. Moreover, the pipeline connection between the hydraulic station 100, the adjusting plate 200, the guide plate 300, and the hydraulic working component 400 is simple, reducing the difficulty of assembling the equipment.

[0036] Preferably, the sub-channel 320 is provided with a second needle valve 520. In practice, the second needle valve 520 can be controlled manually, pneumatically, or electrically to open and close the sub-channel 320. The second needle valve 520 operates synchronously with the corresponding first needle valve 510. That is, when the first needle valve 510 of the regulating channel 220 operates synchronously, the second needle valve 520 of the sub-channel 320 connected to the corresponding regulating channel 220 operates to prevent hydraulic oil from leaving the regulating channel 220 and entering the corresponding sub-channel 320, then flowing through the main channel 310 into other sub-channels 320 and accumulating, thereby improving the response speed of the guide plate 300.

[0037] Specifically, both the regulating plate 200 and the guide plate 300 are preferably provided with mounting holes 530 that are perpendicular to and communicate with the input section of the regulating channel 220 or the branch guide channel 320. The first needle valve 510 and the second needle valve 520 each include a plug 540 that is slidably connected to the mounting hole 530 and is used to block the input section of the regulating channel 220 or the branch guide channel, and a drive cylinder 550 that is installed on the regulating plate 200 or the guide plate 300 and is used to drive the plug 540 to switch positions within the mounting hole 530. In practice, the mounting hole 530 on the adjusting plate 200 is perpendicular to and connected to the input section of the adjusting channel 220, and the mounting hole 530 on the guide plate 300 is perpendicular to and connected to the sub-guide channel 320. The first needle valve 510 is installed in the mounting hole 530 on the adjusting plate 200, and the second needle valve 520 is installed in the mounting hole 530 on the guide plate 300. The inner diameter of the plug 540 matches the inner diameter of the mounting hole 530, and can be inserted into the input section of the adjusting channel 220 or the sub-guide channel 320, thus isolating the input section of the adjusting channel 220 or the sub-guide channel 320. The driving cylinder 550 can change the position of the plug 540, thereby realizing the opening and closing of the input section of the adjusting channel 220 or the sub-guide channel 320.

[0038] Furthermore, the cylinder output end preferably has a connecting rod 560 extending into the mounting hole 530, the outer diameter of the connecting rod 560 being smaller than the inner diameter of the mounting hole 530. During operation, the cylinder drives the connecting rod 560 in linear motion, which in turn moves the plug 540, thus opening or closing the input section of the regulating flow channel 220 or the branch flow channel 320. Because the outer diameter of the connecting rod 560 is smaller than the inner diameter of the mounting hole 530, the cylinder connects to the plug 540 within the mounting hole 530. Even further, the plug 540 preferably has a pressure relief channel 570, which extends through both the upper and lower sides of the plug 540, allowing the spaces within the mounting hole 530 located on both sides of the plug 540 to connect. When the plug 540 is inserted into the mounting hole 530 to close the input section of the regulating flow channel 220 or the branch flow channel 320, the pressure relief channel 570 can balance the hydraulic pressure on both sides of the plug 540. First, by balancing the pressure, the impact of hydraulic oil on the plug 540 and the inner wall of the flow channel can be effectively reduced, extending the service life of the components. Second, it can also improve the system's response speed and reliability, because the pressure balance makes the movement of the plug 540 more stable and rapid, ensuring the efficient operation of the hydraulic press.

[0039] It is worth mentioning that the main input channel 210 extends front and rear, and the input section of the regulating channel 220 extends left and right. In fact, the main input channel 210 can be formed by drilling holes in the regulating plate 200, and a sealing plug can be installed at its end, thereby simplifying the overall structure of the main input channel 210 and integrating the main input channel 210 onto the regulating plate 200.

[0040] Specifically, such as Figure 2 As shown, the input sections of the multiple regulating channels 220 are preferably staggered in the front and back, left and right, which can optimize the flow path of hydraulic oil, reduce mutual interference between regulating channels 220, and enable each regulating channel 220 to obtain a relatively stable supply of hydraulic oil.

[0041] Specifically, the main flow channel 310 is preferably extended front and rear, and the branch flow channels 320 are extended left and right, so that the main flow channel 310 and the branch flow channels 320 form a spatial correspondence with the main input flow channel 210 and the regulating flow channel 220 on the regulating plate 200, which simplifies the pipeline connection and improves the compactness and integration of the system.

[0042] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
